"The Olympics come along once every four years, so it is very important for the players and countries," Floro, who coaches both the senior and under-23 sides, said in a statement. "We have a good group of players and we are going to work hard to achieve a spot in Brazil."

Canada has not sent a men's soccer team to the Olympics since 1984, falling one win short of qualifying for London last time out after losing 3-1 to Mexico in the CONCACAF semifinals..

The confederation covering North and Central America and the Caribbean will send two teams to the 16-country Olympic field in Rio de Janeiro. The third-place finisher at the CONCACAF tournament will face CONMEBOL runner-up Colombia to see who joins them.

Several players were unavailable for the tournament and weeklong camp starting Monday in Alliston, Ont., north of Toronto.

West Ham defender Doneil Henry is injured.

Manjrekar James, who plays his club soccer in Hungary, and Vancouver's Kianz Froese and Sam Adekugbe were unavailable because of club commitments. They may be called up for the Canadian senior friendly against Ghana in Washington, D.C., on Oct. 13, which falls on a FIFA international window.

While the Olympic competition is under-23, Floro had to choose under-22 players for the CONCACAF tournament, which runs Oct. 1-13 in the United States. Teams can augment their squads at the Olympics with three players of any age.

Canada is in Group A with the U.S., Panama and Cuba. Group B is made up of Costa Rica, Haiti, Honduras and Mexico.
